I would go with 4.56's for that engine/tranny/tire combo.
4.10's are a higher ratio for the highway, but you already have overdrive so there's no reason to go with the 4.10's and thus sacrifice usable power in all gears for lower rpms in 3rd. 4.56 will give you better pull in 2nd and 3rd and you can cruise on the highway fine in OD.

I would recommend 4.56s since the tranny has a better OD ratio than the manual tranny. If it were a manual, I'd say 4.10s but 4.56s would work great for the automatic.
